understand this is solved but i want to make it clear for others that come across this, only ever use the upgrade version you are meant to and have paid for, if you paid for windows 7 ultimate upgrade then use that but if you didn't your licence key won't work.
using a registry fix will work as long as it takes for microsoft to come along and do a verification check which they are doing more regularly and will de-authorise your computer and ask for a valid licence key.
in short cracking is not the answer whether you paid for a legititamte copy or not.
edit: my digital life, is a valid source of all microsoft download iso's.
